Hello, I am trying to use the LM317 part on my PSPICE 9.1 Student Version project. I already installed the .lin and .olb, but when I run my simulation I get an error that says "No PSpiceTemplate for U3, ignoring" (U3 is my voltage regulator). I am assuming that its because I have not installed the Digikey database files. It's just that I dont know how to do that. I kindly request your help for this problem
